PCF8563M

HGSEMI · Real-time Clocks (RTC) · SOP-8

PCF8563M from HGSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OSCI input Oscillator input. Connect one terminal of the 32.768 kHz crystal here; a trim capacitor of 5-25 pF is applied externally to OSCI.
2 OSCO output Oscillator output. Connects to the other terminal of the 32.768 kHz crystal. Internal load capacitance is typically 25 pF (15-35 pF).
3 INT output Interrupt output, open-drain (active low). Low-level output current typ. -1 mA at VOL=0.4 V, VDD=5.0 V. Requires an external pull-up resistor.
4 VSS power_in Ground reference (0 V) for the device.
5 SDA bidirectional I2C serial data I/O, open-drain. Requires external pull-up resistor. IOLS min -3 mA at VOL=0.4 V, VDD=5.0 V. I2C slave address: read 0xA3, write 0xA2. Max bus speed 400 kbit/s.
6 SCL input I2C serial clock input. Max 400 kHz. VIH >= 0.7VDD, VIL <= 0.3VDD.
7 CLKOUT output Programmable clock output, open-drain. Selectable output frequencies of 32.768 kHz, 1024 Hz, 32 Hz, or 1 Hz. IOLC min -1 mA at VOL=0.4 V; IOHC min 1 mA at VOL=4.6 V (VDD=5.0 V).
8 VDD power_in Positive supply voltage. Operating range 1.2-5.5 V (I2C inactive) or 1.8-5.5 V at f=400 kHz. Absolute max +6.5 V. Typical IDD 0.25 μA at VDD=3.0 V with CLKOUT disabled.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: PCF8563M
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: pcf8563m-etched.step / pcf8563m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pcf8563m.step / pcf8563m.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
pcf8563m.step 122 KB You want the bare part, or you mark your own boards.
pcf8563m-etched.step 2.0 MB You want the part with PCF8563M already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 489 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
